1. Introduction
1.1 General
The information contained in this manual provides GigAccess™ OFDM 5.8 system
overview and instructions for Planning, Installation, Configuration, and Operation of
both the Access Units, the Subscriber Units including antennas and accessories.
1.2 GigAccess™ OFDM System Overview
GigAccess™ OFDM is a wireless point-to-point and point-to-multipoint broadband
communication system. The basic subsystem is composed of a single sector, which
consists of an Access Unit (AU) and up to 250 Subscriber Units (SU). Each sector is a
stand-alone communication network operating on a star topology with a gateway to
the WAN, which allows two-way communication between the SUs and the WAN via
the AU. A Sector may be extended by sub sectors, which are consecutive to the SUs
within the sector.

GigAccess™ include a Base Controller (BC). The BC is a PC running GigAccess™
Network Management System (NMS) application that monitors and controls the AUs
and their corresponding SUs. The NMS provides SNMP integration, thus connecting
with already existing NMS that service providers might have. Its main purpose is to
configure the AUs and SUs with SLA (Service Level Agreement). Once the AU is
configured, the configuration is stored in the AU and the sector can run autonomously
without the need of a BC (stand alone configuration).

The sector uses a single radio channel frequency with a 20 MHz bandwidth, which
carries up to 36 Mbps data throughput. The system is a frame-based system,
meaning the time dimension is divided into small periods called frames. Each frame is
divided into two parts: downstream part (traffic passing from the AU to the SUs) and
upstream part (traffic passing from the SUs to the AU). The Time Domain Duplex
(TDD) technique is utilized to divide the bandwidth periodically based on the frame
size. The portion of the frame, which is allocated to the upstream traffic, is divided
between the SUs in the time domain using TDMA (Time Division Multiplex Access)
technique.
All the divisions are done dynamically thus allowing the SUs to share the channel
capacity in a very efficient way.

GigAccess™ OFDM 5.8
GigAccess™ OFDM MAC layer is based on IEEE 802.16 MAC standard with additional
proprietary attributes, which allow for special features such as Consecutive AP™.
GigAccess™ OFDM network layer enables routing and QoS queuing of traffic based on
classification of packets using information in layers 2, 3 & 4-7. In certain instances,
QoS queuing can be done using packet information (priority defined by the
management).
GigAccess™ OFDM leverages Orthogonal Frequency Division Multiplexing (OFDM)
technology to deliver high data rates, high spectral efficiency in addition to immunity
to interference and line of site boundaries via patent pending Consecutive AP™
technology, delivering data burst rates of up to 36 Mbps. GigAccess™ OFDM ensures
always-on connectivity to full range of IP-based services, including fast Internet, High
Quality VoIP and Video.
GigAccess™ provides an instant and independent infrastructure, which is immediately
deployable (self installed) with low infrastructure construction and operating costs.
In case of Non-Line-Of-Sight (NLOS) between the AU and the SU due to obstacles
such as tall buildings or mountains, a consecutive sector may be used. In this
scenario, the SU Ethernet output feeds a consecutive AU, which is used as a router
and transmits the input data over the obstacle as shown in figure below.

WARNING: It is the responsibility of the installer to insure that when using the
outdoor antenna kits in the United States (or where FCC rules apply),
only those antennas certified with the product are used. The use of any
antenna other than those certified with the product is expressly
forbidden in accordance to FCC rules part 15.247. The installer should
configure the output power level according to country regulations and
per antenna type.
3) Connect a ground cable between the Outdoor unit and an appropriate
grounding point.
4) Connect the Outdoor-to-Indoor CAT5 shielded cable to the Outdoor unit and
route it to the location selected for the Indoor Outlet. Assemble the enclosed

8) Connect the power supply to the Indoor Outlet power port.
9) Align the antenna and verify connectivity of the Outdoor as follows:
•
For SU - check connectivity to the base controller.
•
For AU - check connectivity to the SU management IP address.
Connectivity check is done by ping instruction.
2.4 AU/SU Outdoor Installation
2.4.1 Site Selection
2.4.1.1 Guidelines for Selecting Outdoor Location
Select the appropriate locations for the outdoor unit using the following guidelines:
•
The outdoor unit can be pole or wall mounted. Its location should allow easy
access to the unit for installation and testing.
•
The AU should be installed where it provides coverage of all SUs in the area it
is intended to serve. The higher the AU or its detached antenna, the better
coverage it can provide.
•
When using a detached antenna, the AU should be installed as near as possible
to its antenna.
2.4.1.2 Access Unit (AU)
Location of the Access Unit is on the Service Provider sole discretion considering local
topology and the desired cover. One (in case of Omni antenna) or several AUs (in
case of directional antenna) forms the BS (Base-Station) – the central of a cell. The
placement of AUs should be such that cells overlap slightly, to guarantee seamless
wireless connectivity everywhere. Neighboring AUs should preferably send and
receive on different channels or different polarization for maximum throughput
(minimum interference).
Page 10 of 41
WaveIP Ltd.
GigAccess™ OFDM 5.8
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may
cause undesired operation.
2.4.1.3 Subscriber Unit (SU)
Location of the Subscriber Unit must take into consideration the following guidelines:
•
Clear line of site to the AU.
•
Height above the ground.
•
Distance between sites.
Path of Clearest Propagation
A propagation path is the path that signals traverse between the antennas of any two
bridges. The “line” between two antenna sites is an imaginary straight line, which
may be drawn between the two antennas. Any obstacles in the path of the “line”
degrade the propagation path. The best propagation path is, therefore, a clear line of
sight with good clearance between the “line” and any physical obstacle.
Physical Obstacles
Any physical object in the path between AU and SU can cause signal attenuation.
Common obstructions are buildings and trees. Any buildings or other physical
structure such as trees, mountains or other natural geographic features higher than
the antenna and situated in the path between the two sites can constitute
obstructions. Install outdoor antennas high enough to avoid any obstacles, which may
block the signal.
Minimal Path Loss
Path loss is determined by several factors:
• Distance between sites – Path loss is lower when distances between sites
are shorter.
• Clearance – Path loss is minimized when there exists a clear line of sight. The
number, location, size, and makeup of obstacles determine their contribution
to path loss.
• Antenna height – Path loss is lower when antennas are positioned higher.
Antenna height is the distance from the imaginary line connecting the
antennas at the two sites to “ground” level. “Ground” level in an open area is
the actual ground. In dense urban areas, “ground” level is the average height
of the buildings between the antenna sites.

2.4.2 Mounting and Wiring
Outdoor Unit mounting and installation will be performed only by personal licensed to
install rooftop antenna equipment where such license required by the regulation
authorities. On any installation case, only professional antenna installers will perform
Outdoor Unit mounting and installation.
Outdoor Unit can be mount on a pole or on a wall.
A general description of wall mount is given in Figure 2-3.
Figure 2-3: Wall mount description
WARNING! When using the system for point-to-multi-point applications, all outdoor
units must be installed with a separation distance of at least 20 cm from
all persons during normal operation.
For a base station or any installation consisting of more than one outdoor
unit (AU or SU) the safety distance for all persons should be at least 2
meters.
When using the system for point-to-point applications, all outdoor units
must be installed with a separation distance of at least 2 meters from all
persons during normal operation
Page 12 of 41
WaveIP Ltd.
GigAccess™ OFDM 5.8
2.4.3 Antennas
2.4.3.1 General
Two types of antennas are available for the GigAccess™ system:
• Integrated antenna
• Detached antenna
The necessary antenna gain depends on the required range and performance.
IMPORTANT!
Antennas must be selected from a list of WaveIP approved antennas.
Please refer to Appendix A – WaveIP Approved Antennas.
According to FCC part 15.247(b):
(1) The maximum peak output power of intentional radiator shall not exceed 1 Watt
(+30 dBm).
(3) If transmitting antennas of directional gain greater than 6 dBi are used, the peak
output power from the intentional radiator shall be reduced below the maximum peak
power (of +30 dBm) as appropriate, by the amount in dB that the directional gain of
antenna exceeds 6 dBi.
That is to say that the maximum EIRP (Effective Isotropic Radiated Power) shall not
exceed +36 dBm.
(ii) Systems operating in 5.8 GHz exclusively for fixed, point-to-point operations
may employ transmitting antennas with directional gain greater than 6 dBi without
any corresponding reduction in transmitter peak output power.
That is to say that the maximum EIRP can exceed +36 dBm in point-to-point
applications.
IMPORTANT! To comply with the FCC EIRP limits, the outdoor unit-transmit power
need to be adjusting according to the installed antenna gain.
Therefore a professional installation of the transmitter is required. The
outdoor unit must be configured at the time of installation by qualified
personal. Fail to comply with FCC rules may expose the installer to
legal liabilities.
2.4.3.2 Tx power
Operating with integrated or detached antenna allowed only after outdoor unit power
setup is confirmed not to exceed +36 dBm EIRP for USA for point-to-multi-point
operation or +20 dBm EIRP for Europe for any antenna used. For point-to-point
operation the EIRP can exceeds +36 dBm therefore configuration will done by a
professional installer. The configuration is only allowed by password of administrator
privilege.
The outdoor unit transmit power configuration is done by the Unit Manager Tool. The
tool consists of dedicated software running on a PC. This PC communicates with the
outdoors unit via the Ethernet and is used to burn the configuration parameters
(including the transmit power) into the outdoor unit. The tool limits the max transmit
power according to the selected antenna, the selected regulation (FCC) and the
Page 13 of 41
WaveIP Ltd.
GigAccess™ OFDM 5.8
selected link type (point-to-multi-point/point-to-point). The installer, if needed, can
select a lower power.
For example: if the selected antenna gain is 24 dBi, the regulation is FCC and the link
type is point-to-multi-point, the tool will set the maximum transmitted power (before
the antenna) to +12 dBm (so that EIRP will not exceed +36 dBm).
The Unit Manager Tool supports two levels of privilege password: regular
administrator user. Since power output levels will affect compliance of the
FCC rules, precautions are built into the system to keep the end user from
the power output level above the regulation limits. Therefore, the
parameters are Configurable only by administrator user:
• Antenna type (detached or integrated)
• Antenna gain
• Tx Power
• Link Type (point-to-multi-point or point-to-point)
user and
unit with
adjusting
following
The above configuration is done with the advanced window of the Unit Manager Tool –
(paragraph 10.5.1).
For open outdoor areas with clear line of sight between the SU and the AU the
suggested maximum distance is given in Appendix C – RF Power and Distance versus
Antenna Gain. For detailed calculations please refer to Appendix B – RF Link Budget
Calculation.
2.4.3.3 Co-located antennas
GigAccess™ OFDM was designed to work with co-located antennas. That means that
two or more units can be mounted close to each other. The minimum distance
between the two antennas should be 50 cm. The two antennas should be of the same
type (Directional Flat Panel Antenna or Base Station Antenna). The main idea is to
utilize polarizations: one antenna in vertical polarization and the other in horizontal
polarization.
Omni antennas are not relevant for co-location.
Note: The FCC 15.203 requirement prohibits the connection of detached antennas
with standard N-type connectors. In order to meet this requirement, the
detached antenna connectors provided on GigAccess™ OFDM models (with no
integral antenna) are non-standard, TNC connector. Only professional
technician will perform the installation.
Note: The distance between any two antennas should be at least 50 cm.

GigAccess™ OFDM 5.8
2.4.3.4 SU Antenna Alignment
Antenna alignment can be done with GigAccess™ Unit Manager software tool. The tool
runs on PC with Windows operating system. In general, low gain antenna (such as
omni antennas) do not required alignment due to their very wide radiation pattern.
High gain antennas have a narrow beam width and therefore require alignment
procedure in order to optimize the link.
Instruction hereunder can be done after completion the connection of the AU and SU
outdoor units to their indoor Outlet.
Please perform the following steps in order to align the antenna:
1. Attach data cable from the PC to the SU Indoor Outlet data port. It is possible
to attach special provided cable marked “data only” to a vacant Outdoor Unit
port.
WARNING! Do not attach standard CAT5 cable from the Outdoor Unit directly to the
PC. Connecting the PC directly to the Outdoor Unit may cause damaged to the PC
Ethernet NIC.
2. Start “GigAccess™ Unit Manager” application.
3. Press on the “Start Session” button (“S” symbol).
4. Select the SU from the popup address window.
5. Select “Installation” at the left menu tree.
6. Rotate the antenna until you get maximum RSSI with minimal PER shown on
the right bars see the installation window in the Unit Manager Tool (Figure
10-5).
WARNING! Do not stand in front of transmitting antenna. Rotate the antenna from
the rear side.
7. Secure the antenna by fastening the mounting screws.
2.4.3.5 Antenna Polarization
The SU antenna polarization must be the same as in the AU antenna. In most
applications, the preferred orientation is vertical polarization. Above ground
propagation of the signal is better when it is polarized vertically. To verify antenna
polarization, refer to the assembly instructions supplied with the antenna set. (The
polarization of integrated antenna is marked on the backside).
2.4.4 Sealing
The outdoor unit must be sealed against rain with the rubber grommets.
WARNING! All Units are factory sealed, seal needed only on Ethernet ports. Opening
the unit will void the GigAccess™ OFDM 5.8 product warranty.

Protection from Lightning
US National Electric Department of Energy Handbook 1996 specifies that radio and
television lead-in cables must have adequate surge protection at or near the point of
entry to the building. The code specifies that any shielded cable from a detached
antenna must have the shield directly connected to a 10 AWG wire that connects to
the building ground electrode.
The ground wire shall be terminated with UL listed lug with a diameter of 0.2 inch
(5.2 mm).
The ground lug will need to be suitable for terminating on aluminum materials, such
as the use of an aluminum connector and aluminum ground conductor.

5. Appendix B – RF Link Budget Calculation
Proper RF link planning ensures that the AU/SU receives sufficient signal power to
maintain the desired Bit Error Rate (BER). The following section gives a brief
description of the basic RF terms and describes the calculation of the maximum safe
distance versus the antenna gain.
A typical radio system is given hereunder:
Gr
Gt
Ct
AU
(Transmitter)
Pt
Cr
Pr
SU
(Receiver)
Figure 5-1: Radio Link – General description
The following variables are used to calculate the link budget:
Pt - Transmitted Power in dBm.
Ct – Transmitter Cable Attenuation in dB.
Gt - Transmitting antenna Gain in dBi.
EIRP – Effective Isotropic Radiated Power in dBm. This is the power radiating from
the antenna, taking into account the output power from the transmitter, connector
losses, cable losses and antenna gain.
PL - Path Loss in dB. This is the signal loss as it travels through the air.
Gr - Receiving antenna Gain in dBi.
Cr – Receiver cable attenuation in dB.
Pr – Receiving Power Level at Receiver in dBm.
Sr – Receiver Sensitivity in dBm (The minimum RF signal power level required at the
input of the receiver for certain performance: E^-5 BER).
F.M. – Fade margin in dB. The fade margin is the amount by which the system gain
plus total gain exceeds the path loss or in other words this is the number of dB
that the received signal strength exceeds the minimum receiver sensitivity. Any
wireless system requires some level of fade margin to compensate for RF path
fading due to weather conditions or multi-path interference. (The transmitted
signal arrives at the receiver from different directions, with different path length,
attenuation and delays. The summed signal at the receiver may result an
attenuated signal). GigAccess™ recommended fade margin at 5.8 GHz is
minimum of 6-10 dB.

Gt = Gr = 22 dBi
Sr (18 Mbps)
= -78 dBm
F.M. = 6 dB
(1)
EIRP = Pt − C t + G t
(2)
Pr = S r = EIRP − PL − F.M . + Gr − Cr
(3)
PL = EIRP + G r − C r − S r − F .M .
(4)
PL = 32.4 + 20 × log(FMHz ) + 20 × log(RKm )
